Can I run "Mesh ‣ Clean up ‣ ..." tools without tabbing into edit mode?
Some of the cleanup operations can be done through modifiers:

Decimate Geometry &gt; Decimate Modifier (Collapse)
Limited Dissolve &gt; Decimate modifier (Planar)
Merge By Distance &gt; Weld Modifier

(Didn't feel right without a silly gif)
